PUNCHINGrMACHINE.

To aZZ whom it may concern:

Be it known that I, ALVAH F. SPooNER, a

citizen of the United States, residing at Sterling,in the county ofWhiteside and State of Illinois, have invented certain new and usefulImprovements in Punching-Machines and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which itappertains to 'make anduse the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to that class of machines used for punching holesin metal,wood, leather, or other material; and it consists, essentially,first, in a novel means of actuating the punch second, in a novelmethod-of actuating the feed by means of the punch; third, in animproved method of seating the punch; and, fourth, ina provision forindicating the number of holespunched.

In the drawings, Figure l is a side elevation of a machine embodying myinvention. Fig. 2 is an end elevation. Fig. 3 isa detail view. Fig. 4 isa perspective view of the guideway to lead the material to be punchedunder the punch.

A A are plates forming the sides of the machine, fastened together inany suitable manner, and furnishing the bearings for the crankshaft Dandrests for the punch bedplate.

B is a punch-standard pivoted tothe bedplate 0 through the ears a, andhaving at tached to .its front side the punch-holder b, which latter isattached to such standard B by a set-screw, e, passing horizontallythrough a vertical slot in the punchrstandard B into a threaded hole inthe punch-holder b. In the I horizontal projection sof the top of thepunchstandard 13, over the upper end of the punch holder 1), is seated avertical set-screw, f, the lower end of which abutting against theupperend of the punch-holder b assists in holding I the latter against theresistance ofthema- I terial punched, andis used to] adjust the punchvertically. In the punchholder bis formed the round vertical hole It,into which the shank-holder of the punch or punches his SPECIFICATIONforming part of Letters Patent No. 289,577, dated December 4, 1883.

fitted, said holder being held in place by the horizontal set-screw g,which passes through the front wall ofthe hole t and abuts against thepunch-shank holder. IWhere two or more punches are used, by placingtheir shanks in the prop er position and securing them in place, asabove described, the holes I made by ,the punches may be punchedlongitudinally in the material punched, or diagonally, transversely, orin any intermediate'position therein. The punch-standard B, at a pointimmediately below the 'setscrew e in its upper projection, isdividedinto two arms, w, which pass backward on each side of the.bed-plate O, and from its point of attachment to saidplate G at c, onthe side nearest the operator, there eX- I tends downward and forwardthe arm '0.

At 9 is shown a feed-clamp pivoted to the side plate of the machine,between which clamp and the punch bed-plate O the material to be punchedis held in position while its forward part .is under the punch h. Theclamp is made to act with sufficient power for this purpose bythe wiresprings g, sprung between studsjj. I I

O is the punch bed-plate, having side projections or lugs, m an, whichare seated in and traverse the horizontal slots 00 x in the sides A A. IThe bed-plate O is also provided with a depression, a, in its upperface, into which wood, leather, lead, or other material is fitted forthe punch h, when in operation, to out against. Upon the lower centralface of said bed-plate G is the bifurcated lug j, to which is pivotedone end of the arm is, the other end of 8 5 saidarm It being providedwith. the oblong hook r, which engages the crank r of the crankshaft D,by which the machineis operated. The crank-shaft D serves the doublepurpose of reciprocating the bed-plate O, with the 0 punch-standard Bthereto attached, and by head draws the material upon the bed-plate C)releasing such punch, thereby gaging the distances between the punchedholes. By moving the screw f forward or back in the slot E the distancesbetween the punched holes can be regulated as desired.

The method I have invented of regulating the number of holes to bepunched at any time is as follows: On the forward leg of the sidenearest the operator I journal the ratchetwheel H, which has in itsperiphery a series of onehundred ratchets and the tongue projection 0,immediately below which, on the front face of the wheel H, is the lug n.A clamp, p, with its single notch z, I attach to any de sired part ofthe'periphery of the wheel. The surface of the wheel H is divided intoten equal parts of ten ratchets each, the said divisions being indicatedon the face of the wheel. Immediatelyunder the upper part of the wheel Hand against the side A is screwed or riveted theT-shaped iron Z, whichmoves on said screw or rivet, but not freely enough to change itsposition by its own weight. This T-shaped iron has on its upper edge thesemicircular projection m, immediately above which,and in the same planetherewith,is the pawl q, riveted loosely to the side A. Attached toone'of the arms of the wheel H is one end of a coil-spring,.3,-saidwspringbeing coiled around the axle of thewheel H, between saidwheel and the side A, and having the other end attached to the side A.

The strip of leather or other material to be punched is introduced underthe feed-clamp 9 and brought. along beneath the guide consisting of theupper part, c, and the adjustable'side piece, 0, under the punch h atthe point. for the first hole or set of holes. Then by the turning ofthe crank-shaft D the cams y on said crank-shaft operating against theend of the arms '10 of the punch-standard B, the said standardworkingupon its pivot at c is thrown=forward and downward, forcing the punchhthroughthe material to be punched. The pieces punched out will flow offdown the-chute b. The. punch remains in such position while thebed-plate O is drawn bythe arm is and crank r back to the point wherethe forward arm, c, of the punch-standard B encounters the trip c, whensuch encounter tilts the standard, carrying its arms 10 downward,

and raises the point of the arm 12 over the trip 6, and thereby removesthe punch from contact with the material to be punched, such materialhaving been-drawn back by the punch h the proper interval between theholes punched. As the'crank is further revolved,

the bed-plate O and standard B are progressed forward along the strap tobe punched to the proper position for the next hole or set of holes. Inits progress the point of the pawl d engages one of the notches on thewheel H and pushes it forward one notch, and the point of thepawl qholdssaid wheel in the position in which it is left by the pawl d. 'Theoperation is then continued until the desired number of holes arepunched. WVhen this result is reached, (the counting-wheel H having beenproperly set,) the clamp p is immediately in front of the line ofmovement of the pawl d,

which in such forward movement encounters the notch z on said clamp, andthrows the forward end thereof against the T-shaped iron Z,which in itsturn revolves its projection m against the pawl q, and holds it fromcontact with the wheel H until the pawl d moves back out of the notch.2, when the spring 3, coming into action, reverses the movement of thewheel H. The lug n on the face of such wheel strikes against the end ofthe T-shaped iron nearest to itand throws it back from its contact withthe pawl q, the latter being knocked into po sition by the tooth 0, andat the next movement I of the punch the point of the pawl d, startsagain to count at the cipher on the wheel. The wheel H is actuated andrevolved one ratchet at each forward motion of the bed-plate O by meansof the pawl 61, pivoted to the side of such bed-plate, and which engagesthe ratehets on the periphery of the wheel H.
